Some roofs amongst my mock-ups (category geometry). I will update the file (with proper cut-outs). Models made by me CC-BY. Basic roofs are fairly straightforward. Making a rounded roof, took less than 5 minutes:
- Draw a wall the shape of your roof (as if the roof stands on its side).
- Select wall and export selection to .obj format
- Import and rotate.
See images below.
Your challenge in this case is making end walls with arched tops. (In the mock-up models above, you will find a half circle which could be used to cover the ends of your he roof when you first draw it.)
